Monitoring PostgreSQL VACUUM processes

Vacuuming is an essential aspect of maintaining a healthy PostgreSQL database. It helps optimize database performance and resource usage by marking dead rows as available to store new data, updating the visibility map, and preventing transaction ID wraparound failure. Monitoring key metrics such as dead rows, table disk usage, and last time vacuum processes ran can help ensure that VACUUMs are running smoothly across your databases. Common issues related to VACUUM-related problems include autovacuum being disabled or not configured properly, lock conflicts, and long-running open transactions. Monitoring PostgreSQL VACUUMs and other metrics can provide a comprehensive view of database health and performance.
